In the gaseous phase, vibrational-, rotational- and translational-energy transfer between small molecules can be observed experimentally from time-dependent optical spectra. Populations in the ...

An international team has developed spherical colloidal particles for the visualization of rotational dynamics. The two-color fluorescent particles have an off-center core that allows tracking of ...

Axonal transport of proteins and materials inside the cytoplasm of the slender axon is essential for a neuron's growth and function. For example, proteins manufactured by ribosomes need to be ...

Mechanics plays a fundamental role in cell biology. Cells navigate these mechanical forces to explore their environments and sense the behaviour of surrounding living cells. The physical ...

Researchers have built a prototype fiber optic gyroscope for high resolution, real-time monitoring of ground rotations caused by earthquakes in the active volcanic area of Campi Flegrei in Naples, ...
